iVilXlNG-MACHINE FOR DRUGS AND CHEMICALS.

SPECIFICATION forming partof Letters Patent No. 299,209, dated May 27, 1884.

Application filed July 2, 1883. (No model.)

To aZZ whom, it may concern:

Be it known that I, ADAM DIOKEY, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Iniprovements in MixingMachines, of which the following is aspecifieation, reference being bad therein to the accompanying drawings.

The object of my invention is to provide a mixing-machine wherein powders, chemicals, and other ingredients can be incorporated together in the most intimate and expeditious manner. Said machine consists of a reoeptacle which is preferably cylindrical, and has at its opposite ends gudgeons or j ournals that enable said cylinder to have an axial rotation imparted to it. Furthermore, said cylinder has at its mid-length two diametrically-opposite' gudgeons or journals that allow the receptacle to be turned over,end for end, all of the abovedescribed journals being adapted to rest in swinging bearings or boxes pivoted to the frame of the machine, by which arrangement of boxes the pair not in use can be swung aside, so as not to interfere with the rotation of said receptacle: This receptacle can be charged either at the side or end; but the preferred plan is to furnish one end of the cylinder with a readily-detachable head or cap, the removal of which affords convenient access to the interior of the machine.

Another feature of my invention consists in fastening to the interior of the cylinder several ranks of fixed blades, agitators, or stirrers, the blades of one rank being pitched at an opposite angle with reference to the blades of the adjacent rank or ranks.

In the annexed drawings, Figure l is a plan of the preferred construction of my mixingmachine, the cylinder being arranged to have an axial rotation imparted to it. Fig. 2 is a similar illustration, but showing said cylinder arranged to be turned over end for end. Fig. 3 is an enlarged end elevation of the cylinder. Fig. 4: is a perspective view of one of the ranks of blades or stirrers.

A represents a suitable frame. to the ends of which are pivoted horizontally-swinging boxes or journal-bearings B B, while the sides of said frame are furnished with similar bearings, G 0, all of these bearings being conoaved at their free ends to admit the gudgeons of the receptacle D. This receptacle or cylinder has at its respective ends journals E E, and-at or near its mid-length two diametrically-opposite gudgeons, F F, the journal E being either attached to or made part of the removable head or cap of said receptacle. As shown in Fig. 1 said journal E projects from a cap, G, having one or more oblique slots, g, with which latter are engaged a corresponding number of pins, (1, of the receptacle D; or, in other words, said cap is secured with a bayo= net-joint; but, as represented in Fig. 2, the journal E is cast with the head H, which latter is clamped to the open end of cylinder D by means of screw-threaded rods I I" and le- Ver-nuts i i.

J is a gasket interposed between head H and the end of cylinder D, by which arrangement the machine (seen in Fig. 2) will be especially adapted for mixing over a fire such ingredients as would be liable to give off explosive vapors or gases.

Fitted within the cylinder D are four ranks of blades or agitators, K K K K, (seen in Fig. 3,) the blades of the ranks K K being arranged obliquely in one direction, while the blades of the other stirrers, K K, are disposed obliquely in the opposite direction.

The operation of my machine is as follows: Receptacle D having been properly charged either with powders, chemicals, or other ingredients to be mixed together, and the cap G or head H being secured in position, the end bearings, B B, are disposed in line with the center of the machine, and the side boxes, 0 O, are swung around so as not to be in the way. The receptacle is then applied to the frame, so as to cause the axial journals E E to rest in the bearings B B, while the radial gudgeons F F now serve as handles wherewith said receptacle is conveniently revolved either to the right or left. It is evident the rotation of said cylinder causes the ingredients to fall continuously to the lower side or bottom of the receptacle; but in so doing the powders, 850., first come in contact, say, with the blades K, whose oblique surfaces shed the ingredients onto the blades K, which latter pitch said powders in an opposite direction. Consequently the powders are compelled to describe a zigzag path in addition to the tumbling action induced by the revolution of the cylinder, the result of which combined movements is to mix the ingredients very thoroughly. After being mixed in this manner, the boxes 0 O are swung in under the journals F F, and the other boxes, B B, are rendered inoperative, as seen in Fig. 2. Cylinder D is now free to be turned over, end for end, which final operation causes the fixed bladesK K K K to act as previously described, and thus completes the mixing of the ingredients.

I claim as my invention- 1. In combination with the revolving receptacle D, a series of blades, K, fixed to the interior of said receptacle, the blades of one rank being set in an opposite oblique manner with reference to the blades of the other rank, as herein described.

2. In combination with the cylinder D, having two pairs of gudgeons, E E and F F, located as herein described, the frame A, provided with two distinct sets of swinging jourrial-bearings, B B and O O, for the purpose specified. I

In testimony whereof I affix my signature in presence of two witnesses.

ADAM DIOKEY.
